Offering a life-size 1:1 maximum magnification and a 5.1″ minimum focusing distance, this Canon EF-S 35mm f/2.8 Macro IS STM lens further distinguishes itself with an integrated Macro Lite LED on the front of the lens to provide additional illumination to close-up subjects.

From The-Digital-Picture:

It is not hard to find room in the bag for the addition of the Canon EF-S 35mm f/2.8 Macro IS STM Lens and especially with the built-in macro ring light and image stabilization, the 35 macro has a very high convenience-to-use factor. With its 1x/1:1 macro capability and great general purpose focal length, subjects abound for this lens. One of the best features of this lens is the wallet impact at checkout – light. Light also aptly describes the lens itself. The image quality delivered by this lens is quite good and it is not hard to justify the addition of this lens to the kit.
